the more i look at these odd/even style cards, the more pointless they seem to me

especially this one... 1 entire card of the set that is "useful" in 1 class, in 1 specific deck, potentially punish yourself even trying to build a deck like this, is epic quality and is situational when you can even play it. how many "ifs" and "whens" can you put on 1 card? + if you get it in a pack as your epic drop and you have no intention to play that deck or don't have baku - it's completely useless...

I dont think this odd-even manacost will work with classes like priest. Having your heropower at one less mana or having it double heal is not too strong, unless you play a contorl deck. And if you play a control deck, why would you play this card????
